NEMESIS Rear Teardown

[NEMESISVETTE]

In true gearhead fashion I tossed a turned all night trying to come up with a plan to find the problem.. When everyone asked what I thought broke at the track I kept saying "driverside differential output shaft"
This afternoon me and my son Gavin got busy tearing it down to see what the damage was. Low and behold it was the driver output shaft.
Here are some pics..

This is the passenger side view of the output shaft and how it protrudes out the middle of the diff. This is how it should look.

,and this is the Driverside view of the Broken off output shaft. and the other part as you can see from next few pics is broke off into the axle.

sucks man. all them horsies and torques no good for nemesissy...do they make all kinds of aftermarket axles etc? i have no clue of anything to do with a vette. hince the stupid question of aftermarket parts.

[NEMESISVETTE]

The C5 Corvette's like mine have a very weak output shaft design.. They improved it with the C6 Vette and there is a aftermarket 300m Hardened output shaft option. Here is a pic to show what I speak of..

[Diggler]

not sure but i think its broke.

[The EnforceR]

That's a lot better than it COULD have been.....prob the easiest fix as far as $ and work involved correct?

[MrDavid]

What caused it all

[Diggler]

perfect spit across the camera. loved it. 2 points for k.simp.

[The EnforceR]

Hahaha dang....didn't even notice that. Good eye.

[2001z]

Looks like you got it all under control gary! That vid of it not moving looks familiar LOL

[crumbie]

Damnations the vette rear looks complicated lol. Put vids on youtube! My laptop is busted and PB murders my BB

[MrDavid]

It would take decades to upload all those vids to youtube. They were 600mb total.

[Whyte864]

Dang Gary that sucks! Let me know if you need any help bro i'm right down the road.

[Green to da Bean]

Tow Ride of Shame gang claims another member.

[SlowC5]

Going with the LPE 300M? What kind of torque do you think requires it and you seemed to be pretty intent on breaking your own build on near slicks. hence why or was it just to test the limits of your build?

throw torque specs/limits of parts out the window with a manual car.

[SlowC5]

What kind of rwtq does a Trophystock start strengthening the rear ass of the vehicle. lol. Really my question was purely scientific, asking Gary about the torque limits of NEMESIS as a mechanical system. He knows it far better than my clean jeans racing and I'd like to learn to get to the dirty panty's phase :-)

Stalled Auto. Big difference in the drivetrain "shock" department.

[trophystock]

It has often been stated that a full throttle start in an automatic car is easier on the drive line then a normal start in a manual tranny one. The shock to the drive train is simply incredible with a stick. The real kicker is it looked like the car was really going to hook, and that was a motor pass if I am not mistaken.

[MrDavid]

and that was a motor pass if I am not mistaken.

You're mistaken on that one Charles. Guns loaded.

Anyone see the poof of white smoke come out the back right as the car jumps forward?

First time at the track, should have made about 3 or 4 shakedown motor passes first. Just sucks he didn't get to run the car more, looks good on the trailer though.

[NEMESISVETTE]

Here are some progress pics.. think most explain them selves. Got 10 hours in this tear down.. Not to bad considering the amount of work it takes for a Corvette.. Headers have to come off on my car to get the Torque tube out the clutch. Pull the TT , Transmission, rear diff and rear Cradle all as one unit. Then separate it all when its down. Anyways here are few pics.

Here is a pic of a Retaining block that must be removed to get the whole gear set out of the differential.
http://i310.photobucket.com/albums/kk433/NEMESISFRC/DSC00538.jpg
You have to Double nut this stud to get it out and then a few allen bolts need to be removed to get the retaining block out. Pics below.

Now she is ready to come out.. Here is pic of it out and the inner of the Diff with out the gear set.

[trophystock]

good progress so far, keep it up. When you done you can swing by and put my silver car back together.

[The EnforceR]

I agree, gotta give him credit for going balls to the wall though, I sure didn't!

Atta boy Gary, already got her torn apart and almost ready to put back together. Man doin work!

[89RABIDFOX]

you need to learn from gary kyle. go balls out every time the car runs. get you a kit and maybe just maybe you will finally enter the 7's. lol.

[NEMESISVETTE]

LOL, Right.. im sure there is nothing im doing or know that you dont... Maybe you can come put my bucket back together..

[NEMESISVETTE]

Getting it apart is easy, its the putting back thats hard.. now I need to make decision on what to do. Upgrade wise.

[NEMESISVETTE]

Funny thing happens when you break your car at the track... You start to Question things, like is this the right car to dump money and time into to make it a drag car? Should I build the rear diff. to the gills? Should I just upgrade the broken output shaft? Should I have the transmission looked at? Should I have the Transmission upgraded and built up? Should I dump the manual all together and put a Automatic in it?
I could go on for days with all the Questions that are running threw my head.. Really thinking about selling the car all together and building a MonteCarlo SS. Im just to burned out on car modding to take on another ground up project.. This Sucks!!

[The EnforceR]

YOu said it yourself, you want a car that can go to shows/cruise ins, run a road course, and run at the track. No need to stray from that goal. I don't think you would enjoy an auto in it...as much as it's driven and also the road course deal you want to tackle. I wouldn't go all out bullet-proof on the upgraded parts, but I would certainly go as deep as you need to ensure that this part of the car should not have to be redone again in the near future.

Break one part, replace it with something that you are almost certain won't tear up again. Because once it DOES break in the future, you realize you should've spent the tad bit of extra money to ensure you wouldn't be re-visiting this srea of the car again. I say all that using common sense, but I haven't really followed that logic with my car either lol. I spun a bearing, and left the entire rotating assembly in the motor minus the crank lol. I was also on a far limited budget than I believe you are, so that's my .02.

[Green to da Bean]

With a manual there is no ensuring you wont visit that area again. It may just take longer, but trust me (and ask me how I know), its still going to break.

throw in those strong ones and run some times for fun. just leave easy.

[Diggler]

are you using captrust for your 401k? they showed us this same thing a few months back.

[MrDavid]

Gary, you'd be crazy to sell this car after all the blood, sweat, tears and money you've put into it. Plus, you've said it a thousand times, you never intended on it being a track car. I agree that you need to upgrade the weak links in the trans/rear, but you don't have to buy the best and most expensive parts you can find. After that, your car won't be "bulletproof" but it is unlikely that you will be back in it replacing something that broke every couple track visits.

If you want a car that will ET, start on the monte. You've got a street king in the FRC. Let it do what it does best.

Thanks guys.. Ya your right David.. its disheartening though.. I've been down this road before with the failure's of the first 2 engine builds.. So I can take it. Just brings me to Question the NEMESIS. Seems the advise I have gotten from those of you I have spoke with is the same thing I think to be my best plan of attack.. Upgrade the output shaft with a Hardened set.

[MrDavid]

With minor upgrades to the drivetrain you can have fun at the track with "less" worry and be even more confident in it when taking names Mexico. Matter of fact, its been a while since Nemesis has claimed another victim in Mexico.....

[MIKE02TA]

Keep the 6speed, upgrade the output shafts, got the rear diff. braces, slide the clutch with leaving, and give it the squeeze before the 60ft and have fun! Can't try to kill it man.

[NEMESISVETTE]

This is a Z Grip Textraillia clutch.. Ive said it many times.. I did try and slip it.. the material is to tough.. Its a light switch.. OFF OR ON. I know how to Slip and Squeeze; just some times it just Grabs and thats what she did Friday.. If you watch the Video you can see me sit for a sec before going.. I actually started the slow release of the clutch on the 3rd Yellow and slowly let of the clutch and BAM!! it grabed and the car dead hooked!..

[406malibu]

damn that sucks. You'll regret selling it if thats the route you take though. I'm not a huge C5 fan, but even I wouldn't get rid of that beast of a ride. If it doesn't brake at some point, you're not driving it to its potential :)

[1997b4c]

keep your chin up man. NEMISIS aint no bitch she wouldnt sell you out!!!!!!!!!

[98chevyman]

Gary i hear the waabulance coming down the street after you man! SHit of all the hell and motors rear ends clutches spending 10g at hawks on a motor and about 6g on this last engine plus the 2g for the 9inch i have thought of selling my car over and over again. Its self pity man> Get those balls out that u have sat somewere and put that thing together! my god man i wish i could give u all the grief ive had in camaros alone after having 3 totalled within 6 years and having a ss that i have maybe put 25,000 miles on since i bought it 4 years ago.

YOu know as well as i do cars are not reliable not matter what. Hence why we call this car thing a hobby. lol Not a job. if the car is becoming a job take the loss and move on to upgrade(as i did) and just get it to the point of what brings the enjoyment out of the vehicle to u. DAMN!

[MrDavid]

Thats about the truth Kent. If anyone on this board has had some shitty build luck, its Kent. My car might be in second place.

[98chevyman]

Daaaaaamn right!

[NEMESISVETTE]

Didnt know it was a competition to Fail...Of you guys win.. You FAIL harder than I do.

[89RABIDFOX]

Anytime any of us have something break it causes us to tho.k about waking etc. I went theu it w the silver car. Then I just decided to keep it bc I lived it and it got to where I didn't care to work on it. Then I smashed a wall and end of story. Lol.

[Napalm331]

What's the next move Gary?

[NEMESISVETTE]

What's the next move Gary?
Man I dont know!! lol... Im going to order a aftermarket hardened output shaft to replace the broke one.. also new seals gaskets ect.. also that busted belleville ring.. and put it all back together.
The one thing that got me pissed today was the broken of part of the output shaft that has yet to be pictured, its stuck in the axle.. Well I was working hard on getting it out of the axle and it pushed further into the axle and I guess it pushed out a seal and now all the dop came gushing out!!!! @#$%^&*&^%$^$!!!!!!!!!!!!!!!!!!!!!!! FUWKKKKKKKK!!!!!.. Dont know what to do bout that... Guess I have to buy a whole new axle or figure out how to separate it and get that piece out and refill it?

[NEMESISVETTE]

This is what im talking about.. You can see the other broken piece in the shaft.. Well it went all the way back into the boot and pushed out a seal and now dop is gushing out and that broken piece of the output shaft is in the boot.

how about a strong magnet to full that out.? harbor freight or nothern tool has some serious ones. maybe a little astroglide to slide it right out

[MrDavid]

Been meaning to ask, are you going to stay with 3.42's or swap to 3.73's while you've got it down this far?

[KUTTER]

. maybe a little astroglide to slide it right out

:rrofl:

Hella strong magnet might work,but seems like it would magnetize the whole thing also depending on whats made of what. Or perhaps just piece metal with flat end skinny enough fit down there, throw some super glue on end of it gently pull it out?Air pressure from opposite end, if possible?

[NEMESISVETTE]

All good idea's how ever the damn piece slid back into the boot.


http://i310.photobucket.com/albums/kk433/NEMESISFRC/DSC00530-1.jpg

maybe i can take the V clamp off the boot and get it out and fix the seal and replace the dop oil. dont know. I found a used axle for $100 bucks but damnnn I dont want to buy one if I can fix this situation.

[KUTTER]

I think you can fix it.. I BELIEEEEEEEEEEEEEVE

EDIT= LMAO at that pic looks like you got your first session in the tatt removal

[TurboLSX]

jb weld something to it, then when it tries pull it out

[KUTTER]

I mean how heavy is the thing?? Is it just real snug in there? Alot those hand wand pick up tools say lift up to 8lbs. Id say get 3 that suppose to lift 8lbs, bind them together, hit the surface with all three slowly work it out. If not take em back. Then move on to glue/weld/adhesive but that be my last option just because MAY leave crap in there

[trophystock]

just drill and tap it, screw a bolt in and pull it out, done deal.

[Whyte864]

IDK if he can fit a drill and screw down in it since it fell down into the boot. Gary i'm off work tomorrow, gimme a call. I work for free as long as I can learn more about LSX's haha

[NEMESISVETTE]

tried that.. the material GM used is pretty aggressive stock.. I was able to drill it at the cost of it eating up 4 drill bits.. then the pushing and pressure pushed it threw the shaft into the boot.. cant get to it now without takin the axle apart now.

[NEMESISVETTE]

Thanks bro, but I work 12 hours. im off Wed and Thurs. Im sure to get it out one way or another then.:wrenchbanana:

[MrDavid]

Were those carbide bits that it chewed up?

[NEMESISVETTE]

Were those carbide bits that it chewed up?
Na, task force bits at best.., but we are talking bout tempered steel here.. That's not option anymore anyways.. It pushed back into the axle boot now..I gotta figure way to get it out.. I'm sure I can snap clamp off and get in there.. Don't know

[TurboLSX]

gary what if i tack weld something to it. with that let you pull harder ?

[bhice]

This is what im talking about.. You can see the other broken piece in the shaft.. Well it went all the way back into the boot and pushed out a seal and now dop is gushing out and that broken piece of the output shaft is in the boot.

http://i310.photobucket.com/albums/kk433/NEMESISFRC/DSC00530.jpg

you can take that clamp off. they sale replacement clamps for those. that would be your best bet instead of spending $100 on a used axle. try autozone or a store similar to them.

[NEMESISVETTE]

Got it all fixed up this morning.

[bags50lx]

gary what if i tack weld something to it. with that let you pull harder ?

Won't work. I've seen your welding abilities. Now Bondo, that ought to hold it.

[Diggler]

gary PIIHB this morning and it pulled the piece right out.

[1997b4c]

Won't work. I've seen your welding abilities. Now Bondo, that ought to hold it.

lmmfao

[NEMESISVETTE]

Nemesis been know to brake a shaft off in-ya

[trophystock]

Please tell me you didn't suck it out.

[NEMESISVETTE]

Please tell me you didn't suck it out.
It was a option but you never showed up..lol So I separated the boot, got broken piece of shaft out, replaced and seated new seal, put some new CV joint grease in it, lined up ball barrings and reclamped the boot to the shaft.

[trophystock]

Have you got the shaft from someone yet?

[NEMESISVETTE]

Have you got the shaft from someone yet?
I get it from lots of people lately.

The toughest output shaft money can buy should be here tomorrow. I hope so at least. I ordered :

LH 300M output shaft from DTE
RH C6 Z06 Side gear
RH C6 Z06 Side gear retaining ring
2 Axle Seals
2 Side Cover O-Rings

[NEMESISVETTE]

Pretty sure it will be back apart before 2011..lol Once you strengthen a weak part; something close by breaks even bigger! lol Im gonna say diff case or Transmission shaft.

[MrDavid]

As long as you can get at least 1-2 passes out of it...

[NEMESISVETTE]

My goal is to atleast break the first beam..lol

I don't own street tires anymore fools. 275 radials or 26" Slicks....pick your poison.

Sorry Gary. No more. :gethim:

Well borrow that ish. I got some salad shooters you can run lol.

[MrDavid]

My tires are legal on the street :)
